Not all engines are the same and you want to make sure your Precleaner fits your engine like Cinderella's slipper, perfect... or should we say your Cylinderella.

We have run the numbers on CFM consumptions across all types of engines. In fact, it is the science we pride ourselves in. Decades of field testing forged the range of different Series 9000 Precleaners and adaptations to perfectly match the environment and CFM requirements of each engine to maximize particle separation. It's the Spin-Science applied across the design of the Dome and rotor that makes The Sy-Klone Series 9000 the market-leading engine Precleaner*! (or PreFilter*..  potato-potato? ;-p  depending on how you want to say it. )


Adapters are either included in the price of the item or can be purchased separately.  


Easily added to universal snorkel kits like the Safari, RuggedRidge, AEV, Bravo snorkels. With adaptation, it fits almost all snorkel head inlets.

The snorkel Precleaner is a patented technology that uses the centrifugal force generated by the rotor inside of its dome to separate particles out of the air before going into your snorkel. 

The pre-cleaner uses the airflow from your engine intake to spin a rotor which creates a cyclone style effect inside the dome pushing large particles to the inner wall of the dome where they are ejected. This makes the worries of rain, snow or lots of dusty on a dry day from coming into your snorkel and clogging your filter go away! With this pre-cleaner, you also don’t need to worry about adjusting your snorkel head or dumping out a pre-cleaner that catches debris.
